This is a bit like saying: The biggest problem of modern rockets is the shape of their sails. It sounds cool to laymen, but of course it doesn't make any sense.

A dynamics processor is something taking a value, and returning one. Instantly.

Here's a dynamic range compressor:

y = tanh(x)

What exactly is the problem of finding out the value of y?!

A compressor doesn't have to "wait" for results. It simply looks at the input, and returns an output. Maybe the best counter example, perfectly showing how ridiculous this idea of a "delay problem" is: Digital clipping.

No. There is no general problem. Zero difference to analogue circuits. Takes an input, returns an output. Simultaneously.
